Compress a single file by running tar -zcvf file.Ĭompress an entire directory by running tar -zcvf file. xz -k file.txt This can also be done with the -c flag as below. Unlike xz and gzip, tar doesn’t delete the input files after it creates the archive.Compress multiple directories file by running. Which xz compression level does tar pick? It depends on our version of tar, but it probably is the default compression level 6. Tar allows setting the compression program through the –use-compress-program option. Unlike xz, tar doesn’t delete the archive file after the extraction is completeĥ.Because of the v option, tar shows which files are extracted from the archive.tar does this automatically by inspecting the file and detecting the xz compression We don’t have to tell tar to decompress with xz.We decompress the file and extract its content into the current directory.Please note that we removed the J option here because –use-compress-program already sets the compression program.ĭecompressing a tar archive with xz is also a single step and identical to gzip (except for the different file extension): tar xvf Here, we specify the minimum compression level 1: tar cvf -use-compress-program='xz -1' *.csv We use this option to set the compression level, too. ![]() Previously, we stated that xz creates smaller archives than gzip. To test this claim, we used the same 818 MB CSV file, and the same computer with six CPU cores and hyperthreading, as we used to test gzip in Linux. ![]() With compression level 5, xz produced the smallest archive at 29 MB, which was 69% smaller than pig z.xz used compression level 1 out of 9 for this In the same 4 seconds, xz compressed the file to just 48 MB, which was 49% smaller than pigz.Higher compression levels didn’t produce meaningfully smaller archives At compression level 7 out of 9, pigz compressed the 818 MB CSV file down to 95 MB in 4 seconds.pigz does this by default, xz because of the -T0 option Both archiving tools saturated the CPU in our tests.We compared xz to pigz, a gzip implementation that uses multithreading for faster compression and decompression. But at 70 seconds, xz also took nearly 18 times as long! Compression levels six and beyond hugely increased the compression time for a negligible 1% reduction in archive size You can use XZ to compress videos and files that are unbalanced. files have the same name because they are created with the tar command, which is used with Linux or UNIX operating systems. So we’ve demonstrated that xz does indeed create much smaller archives than gzip.
